You are quite right in observing that natural selection reduces the information content of the gene pool. It is the function of mutations to increase that content. A diverse (high information content) gene pool is required to produce sufficient variation on which natural selection can act. Thus both random mutation and natural selection are essential to evolution.So, clearly, you are conflating ideas. I used the word FACTUAL. You cannot say that because Darwin merely proposed a hypothesis that “natural selection” could explain origins, that such a thought represents a FACT. It does not. The problem with all of you who keep criticizing my posts is that you apparently don’t understand the most basic fact: that “evolution” cannot be equated to “evolutionary origins”. Please, quit conflating the two subjects. If Darwin had known what we know today, he would have known that what he called the process of natural selection DECREASES genetic diversity over time, meaning that in the shuffling of genes which produces offspring (in organisms that reproduce sexually) certain gene forms (i.e. alleles) commonly get removed from populations (at least certain populations under environmental stress, let's say), especially during the phenomenon called bottlenecking. Ironically, this phenomenon has been touted as very important to the production of new population phenotypes. And that is actually true, but the reason does not support naturalistic ORIGINS of genes.
Dogs demonstrate many different phenotypes than their ancestor, the Grey Wolf or something much like it. Yet, this does not mean that dogs somehow accumulated MORE GENES than their ancestor. It is a well-known fact that dogs have more diseases than the wolf and they live shorter lives than wolves live. Why? They have lost genetic diversity. So, the fact that you seem incapable of seeing or accepting is that as “evolution” happens (i.e. Wolf-to-dog), phenotypes can expand while the genotypes are actually contracting (for lack of a better way of explaining). This represents supreme irony that is inconsistent with Darwin’s theory, yet very consistent with Creation/I.D. theory.
An example of the "bottlenecking" you refer to can be seen in forced selective breeding, where the selection is stringent and depletes the information content of the gene pool of the breeding population faster than it can be replaced by natural means.
